Amounts in each company's own currency, US$ unless marked (a foreign company may report in another), each company's latest fiscal year from its 10-K, or 20-F or 40-F for a foreign company. Growth rates compare with the year before; the five-year rate is the average a year. Free cash flow is cash from operations minus capital spending; return on capital is after-tax operating income over the money invested in the business; P/E is the last close over the latest earnings per share. Banks are measured differently (return on equity, efficiency ratio), so some rows apply to one company only.
